is required to use the LATTE package and its fix latte command in a

LAMMPS input script.

developement effort is led by Anders Niklasson, etc at LANLS.

The LATTE development effort is led by Marc Cawkwell and

Anders Niklasson at Los Alamos National Laboratory.

To download, build, and install LATTE as a library on your system,

follow these steps.  We are working on scripts that will automate this

process.

follow these steps: 

- Download or clone the LATTE source code from: 

  https://github.com/losalamos/LATTE. 

Go to this web site: https://??? and download a current tarball.  The

tarball you download is "latte-??.tgz", which can be unpacked in this

directory or wherever you wish:

- Modify the makefile.CHOICES according to your system architecture 

  and compilers.

tar xvfz latte*tgz

- Set the MAKELIB flag to ON in makefile.CHOICES and finally, build the 

  code with the make command. 

Note that if you unpack and build LATTE in this directory, when you

lost. So you likely want to build it somewhere else. The recommended 

place is the home directory.

To build LAMMPS with the LATTE library you should follow the following 

instructions:

Build instructions for LATTE library ...

- makefile.lammps.* to makefile.lammps in the /lammps/lib/latte directory. 

When you have successully built the LATTE library, you can build

LAMMPS with the LATTE package installed:

- Change the path, flags and compilers on the makefile.lammps according 

  to your compilers, architecture and the LATTE location.

- Finally, you should execute the following commands: 

  $ cd lammps/src

  $ make yes-latte

  $ make g++ (or whatever target you wish)
